Abstract

PURPOSE:To make possible to find early enough the conditions of clogging of cooling pipes of a cooler, by monitoring the difference between the inlet temperature and the outlet temperature of a fluid to be cooled in a auxiliary cooler of a geothermal power plant. CONSTITUTION:The difference of temperatures detected by temperature detectors 12, 13 is reconded in an arithmetic unit 15, and this difference and a predetermined value of a predetermining unit 16 are compared by a comparator 17. Further, the temperature of the detector 12 and a predetermined value of a predetermining unit 15 are compared, and if the value of this temperature is at least the predetermined value, and the difference of temperatures detected by the detectors 12, 13 becomes at most the predetermined value of the predetermining unit 16, a command is sent to a starter 20. Thus, a ball circulating type washing apparatus 9 is actuated to wash the auxiliary cooler 8. Thereafter, if the washing is completed, a stopping command is dispatched from the comparator 17 to the starter 20 to stop the washing apparatus 9.
